Hello all,
I've got an odd issue which I'm hoping someone can offer a steer on.
I have the EE 1.6 Gb Full Fibre Busiest Home package with a Smart Hub Plus.
All seemed to be working fine until my original Smart Hub Plus failed in Jan 2025. This was attributed to a bad firmware update, and a new hub was sent out. I connected this up and again everything appeared to be ok, until colleagues at work started complaining that my video during MS Teams calls was regularly freezing. On my end, I didn't see any issues - I could see and hear everyone else fine so it came as a surprise. Setting up a test meeting that just included me, I recorded myself and when playing back immediately found that the video and audio both freeze and stutter. This is readily reproducible, although sometimes the performance is extremely bad with the video completely frozen. Strangely, this only affects the MS Teams desktop app, with connections via the web browser still being good quality.
So far, everything else seems ok - stable and fast connection (getting around 1.6 Gbps routinely).
Here's what I've tried so far:
This suggests to me it might be some network infrastructure issue, rather than a problem with the Smart Hub Plus or with the laptop / Teams. Could the route the traffic is following make a difference? If so, how would I go about pinpointing this? The Microsoft 365 connectivity tests don't flag up anything obvious.
After much testing to convince myself there was an issue with the connection I called EE and an engineer visited. He indicated there had been some problems with the Smart Hub Plus on fast connections, tried to run a series of tests but these didn't complete. Reason unclear. However, he was confident that the new Smart Hub Pro would resolve the issues although he wasn't allowed to issue one himself.
Engineer left, job appeared to be closed, then I got a message from OpenReach asking me to arrange a call so that equipment could be delivered. I did, got put through to EE, with the guide saying that I really should have had the Smart Hub Pro already and that he'd get one sent out, although the process for doing this was very difficult. That was almost a couple of weeks ago. Being concerned this wasn't being progressed I got back in touch - over multiple calls now, once I get past the agent telling me I've got a very fast connection and they can't see an issue or find open jobs, when they review previous notes there's a record somewhere to an order being placed, but no-one can find out what. It appears I'm now down as a new customer and something needs to be progressed by the "New IT" team, even though I've been with EE for over a year.
So, perhaps a Smart Hub Pro will be sent out, which will be good because it sounds like I'm entitled to one on my package.
However, I'm not convinced the hub itself is the issue, given that the Asus router performs similarly, except when a VPN is active.
Does anyone have any thoughts about what might be happening?
Thanks!

Hey there @QuantumPhys.
Welcome to the EE Community, and thanks for taking the time to share so much details on what you've tested so far with this!
Did you mention to the engineer that visited that you had tested this with the Asus router already?
If you're confident doing so as well, you could also try setting up a PPPoE network on your laptop and plug directly into the ONT and test without any separate router in between.
You can find all of the settings for this here:

Thanks @Peter_W ,
The testing with my Asus router was after the engineer had left and I hadn't heard any more about the Smart Hub Pro I was expecting. When the engineer was at the house he was pretty convinced there was a router issue because his tests wouldn't complete. My impression was that the router needed to be exchanged before any more in depth investigation would be undertaken.
Connecting the laptop directly to the ONT is a good suggestion. I'll try that next opportunity I've got and let you know what happens!

Hi @Peter_W,
I managed to link the laptop directly to the ONT, establish a PPPoE connection OK and run some tests.
The Teams performance was similar to via either the EE or Asus router, perhaps slightly better, although definitely with noticeable stutter on both video and audio.
General performance test results were:
Fast.com - 520 Mbps
Speedtest.net: https://www.speedtest.net/result/17700510603
Thinkbroadband: https://www.thinkbroadband.com/speedtest/1746549527141756555
At the end of the session I tried another call using a 4G hotspot via my phone, and as previously, the Teams call quality was excellent - very clearly superior to when using the direct connection via the ONT.
Any thoughts on what to try next, or whether this may be pointing towards where a problem may lie?
Thanks,
Andrew

@QuantumPhys Tether your phone to the laptop and test.

Hi @JimM11 ,
Thanks for the suggestion.
Here are the results. Essentially the EE results are still poor, despite the faster connection, but various connections via my phone are all fine.

@QuantumPhys As far as i can see, with the copy that you have posted and below, you have a serious upload problem and it is not going to get better until you get that fixed. Download may be ok but for teams/zoom etc the upload is just as important. Question for you do you have or are you using any kind of wi-fi booster device on the network?

@QuantumPhys When cleared for viewing you can take a look see. Also the link below to a very detailed speed test and look closely at the details boxes for the upload side of the speed test's. There are 2 thing's that you need to do, 1. is network connect your laptop to the Pro router that you have, 2. vary the testing times to get a picture off what is going on connection wise. 3. do not care what bundle you say you have got, there is an upload issue, may not be you or your home or your connection but there is something going on around your fibre.

@QuantumPhys Two quick captures but his time on a PC with a Ethernet direct connection. Again when cleared for viewing.

Hi @JimM11 - here are some outputs from tests run at different times of day. Each time the laptop is connected by Ethernet cable to the Smart Hub Plus.
1000 in the morning
1200 noon
2000 in the evening
I can't see anything obvious in these.
Teams / Zoom calls are poor quality each time.
If I use a VPN the quality is fine but because it's a corporate laptop I can only do this when the VPN client is running on my old Asus router, either with the Asus router connected to the ONT and using PPPoE or with the Asus router acting as an access point to the Smart Hub Plus. (The issues with Teams/Zoom persist when the Asus router is connected to the ONT but without the VPN running.)
I've monitored the network traffic and something strange is happening with STUN packets. I tried putting the laptop in the DMZ and also changing NAT to FullCone on the Asus router and neither makes any difference.
